The adapter's config.url of axios 0.19.1 and above dosn't include baseURL, but axios 0.19.0 and below includes baseURL.

Describe the bug
The adapter's config.url of axios 0.19.1 and above dosn't include baseURL, but axios 0.19.0 and below includes baseURL.

To Reproduce
I provide an example of running online: https://jsfiddle.net/r70u4wfs/, just change the axios's version, see the log of adapter config.

const newAxios = axios.create({
  baseURL: 'https://httpbin.org/get'
})

newAxios({
	url: '/test',
  adapter: config => {
  	console.log(config)
    return new Promise((resolve, reject) => {
    	resolve({data: {}})
    })
  }
}).then(res => {
	// console.log(res)
}).catch(err => {
	console.log(err)
})

Expected behavior
Different versions should have the same performance. Version 0.19.1 and above should also contain baseURL.

Environment:

• Axios Version [0.19.1+]
• OS: [windows 10]
• Browser [Chrome]
• Browser Version [80.0.3987.163]

Additional context/Screenshots
Version 0.19.1 and above: dosn't include baseURL

Version 0.19.0 and below: includes baseURL

Hi JihuYu,

I am looking into it, I have validated that this does happen. Interesting to note is that if one is to do it like this:

const axios = require("axios");

const instance = axios({
    baseURL: "https://httpbin.org"
});

instance.get("/get")
    .then((response) => {
        console.log("axios@0.19.1: ", response.data);
    });

You do end up with the call working successfully. I will look into the issue further and let you know.

I think it should be consistent because many adapters rely on config.url. I hope you find out the reason as soon as possible.

Hi @yujihu,

Did you have a look at #2751? I think that might help as there is a lengthy discussion over there about this and similar issues. Please have a look and comment over on that issue if you have additional comments.

Thanks

@yujihu I am going to close this for now so that we can rather maintain the discussion over on #2751
